Answer: A. Wind
Diagnose the question type - a typical biology numerical. We are after the quantity the stem asks for. Tool of choice - pressure P = thrust / area = F / A, measured in pascals (N/m^2). Rearrange it for the unknown before substituting. Numbers in: pressure P = thrust / area = F / A, measured in pascals (N/m^2). Common-sense check: the same force on a smaller area. Lock in option A) Wind. Trap-watch: option B) 'Convection current' is incorrect: Convection current: warm fluid rises, cool fluid sinks; option C) 'Ocean current' doesn't hold - Ocean current: large-scale movement of sea water.
